APPLICATIONS
GENERAL DESCRIPTION
The OM4068 is a low-power CMOS LCD driver, designed
to drive Liquid Crystal Displays (LCDs) with low multiplex
rates. It generates the drive signals for any static or
multiplexed LCD containing up to three backplanes and up
to 32 segment lines and can be easily cascaded for larger
LCD applications. All necessary functions for the display
are provided in a single chip, including on-chip generation
of LCD bias voltages, resulting in a minimum of external
components and lower power consumption. A 3-line bus
structure enables serial data transfer with most
microprocessors/microcontrollers. All inputs are CMOS
compatible.
